What is Vespel polyimide?

What is Vespel polyimide?

DuPont™ Vespel® Polyimide is an extremely high temperature, creep resistant plastic material that is often used in high heat environments where thermoplastic materials lose their mechanical properties.

What is Vespel sp1?

Vespel® SP-1 is an unfilled base resin grade. SP-1 provides maximum physical strength, elongation, as well as the best electrical and thermal insulation valves.

Where is vespel used?

Vespel is mostly used in aerospace, semiconductor, and transportation technology. It combines heat resistance, lubricity, dimensional stability, chemical resistance, and creep resistance, and can be used in hostile and extreme environmental conditions.

Is vespel electrically conductive?

DuPont™ Vespel® SP-1 unfilled offers superior wear and insulation properties with operating temperatures from cryogenic to 260°C (500°F). Vespel® SP-1 has low electrical conductivity and the highest elongation and purity of the SP family.

What is polyimide used for?

Polyimides offer excellent mechanical properties and thus find use in applications that demand rugged organic materials, e.g. They are available for use as plastics, films, laminating resins, insulating coatings and high temperature structural adhesives. Polyimides exist in two formats: thermosetting and thermoplastic.

Is vespel machinable?

DuPont™ Vespel® shapes are relatively easy to machine because of their inherent mechanical strength, stiffness and dimensional stability at machining temperatures. In addition, they can be machined with standard metalworking equipment to produce parts to tolerances once considered too close for plastic materials.

Is vespel a thermoplastic?

Vespel® is a high-performance polyimide-based thermoplastic material with notable characteristics: it withstands wide temperature ranges; it is wear and chemical resistant; it has excellent mechanical and insulation properties; it has natural lubricity; and unlike most polymers, it does not produce significant …

What is polyamide example?

A polyamide is a polymer with repeating units linked by amide bonds. Polyamides occur both naturally and artificially. Examples of naturally occurring polyamides are proteins, such as wool and silk. The transportation manufacturing industry is the major consumer, accounting for 35% of polyamide (PA) consumption.

What is the difference between Dupont™ Vespel® polyimide SP-1 and SP-3?

DuPont™ Vespel® Polyimide SP-1 is unfilled and offers superior electrical and thermal insulation properties. DuPont™ Vespel® Polyimide SP-3 for unlubricated sealing and low wear in vacuum or dry environments with low outgassing. DuPont™ Vespel® Polyimide SP-21 is a graphite-enhanced grade with low-friction properties.

Why choose Vespel® SP polyimide rods?

Vespel® Polyimide’s superior mechanical properties, chemical resistance and wear resistance makes it a popular choice for aerospace, farming, semiconductor processing, automotive, industrial and transportation applications. Vespel® SP polyimide Rod is produced from advanced polymers developed by DuPont.
